I am a cybersecurity professional specializing in ethical hacking, digital defense, and vulnerability assessment.
My primary focus is on proactively identifying and mitigating risks before they can be exploited by malicious actors.
I am strongly committed to safeguarding digital assets and anticipating adversarial tactics to remain one step ahead.

In addition to my cybersecurity expertise, I have a solid background in software development.
I design and implement Python-based tools for automation, threat intelligence, and SIEM optimization.
By integrating security and software engineering, I deliver efficient, resilient, and intelligent defense solutions.

I've been pursuing this journey with passion since 2021.

• Offensive & Defensive Security
• Rust & Python Development
• OSCP Preparation | Threat Hunting | SIEM Automation
• Red Team & Blue Team Simulations
• CTF Builder & Participant

My goal is to master every domain of cybersecurity — from threat intelligence to digital forensics, protocol analysis to security automation. I believe true expertise comes from understanding the full spectrum: attack, defense, detection, and response. I build tools, study behaviors, and explore systems to uncover how security truly works — end to end.

Because every system hides a story — of trust, logic, and flaws.
Exploring these layers isn't just about breaking things;
it's about understanding how they fail and how to make them stronger.
I believe true security comes from curiosity, ethics, and persistence.

I am actively developing expertise across key cybersecurity domains, emphasizing hands-on experience and continuous learning.
